Local disclosure of protected data
Published Dec 16, 2022 · Updated Apr 21, 2025
Information disclosure in the Android kernel modem on supported Pixel devices allows local users to read protected data. Google has not published the affected modem routine or the out-of-bounds operation performed on untrusted input. Exploitation requires low-privileged local access and affects confidentiality only; the public record identifies no integrity or availability impact.
